>Whatever I know or think I know about earthquakes, nuclear reactors, climate change, Afghanistan, Iraq, and Middle East uprisings (among other matters) is tentative knowledge acquired secondhand. I choose my sources of expertise and information and can only hope I choose them wisely and that skepticism and reason provide some defense against being regularly deceived. The fears, fantasies, and falsehoods that accompany what seems like a permanent state of global emergency require eternal vigilance.

Consider the power of political lies that exploit partisan biases and loyalties, left or right. People will often believe a lie disseminated by a source they trust or with whom they want to identify; policy positions on matters of fact as well as belief, from climate change to abortion rights, become ideological badges of belonging. Attack the accuracy of a foundational, ideological "fact," try to expose a political lie, and its believers will resist your critique of it or they'll dismiss the significance of the truth. A recent New York Timesprofile of New Jersey governor Chris Christie illustrates the dynamic.

People will often believe a lie disseminated by a source they trust or with whom they want to identify.

"Christie's Talk is Blunt but Not Always Straight," the headline declares. Statements "at the core" of the governor's attack on public sector unions, like the claim that state employees don't pay for health care insurance, are "inaccurate" -- in other words, they're flatly untrue. But who's to know? A political scientist quoted by the Times observes, "Clearly there has been a pattern of the governor playing fast and loose with the details. But so far, he's been adept at getting the public to believe what he says."

It's not surprising. As a general rule, the general public doesn't have the time, energy, resources, or inclination to delve into details. And when a New York Times reporter does the delving and presents the governor's supporters with pesky facts that directly contradict his claims, the public may dismiss the contradictions as reflections of an elite, liberal bias (if they regard the Times the way I regard Fox News). Or they'll follow the lead of Christie communications director Maria Comella and resort to the truthiness defense: When questioned about the governor's misstatements, she boasted that he was "engaged directly with the people of New Jersey" while the Times was engaged in a story that "splits hairs."

Comella's response captures the cynicism of political operatives for whom there's less than a hair's difference between a truth and a lie. When they're caught lying, who's to care? But I don't mean to denigrate the failure of many lay people, focused on their own lives and their own mishegas, to sort out the details of policy disputes. The tangled web of deceptions we were once warned not to weave conceals the truth much more often than it exposes a lie, because so few people are willing or able to unravel it. You can see this dynamic at work in complex white-collar cases, in the efforts of federal prosecutors to clarify alleged economic crimes.

Consider the Galleon insider trading case against hedge fund billionare, Raj Rajaratnam, now underway. The Timesreported that the prosecutor tried to simplify the case in his opening statement, while the defense attorney outlined its complexities:

The styles and strategies of the two lawyers during opening statements were markedly different. Mr. Streeter, the prosecutor, zeroed in on just a few instances of alleged insider trading by Mr. Rajaratnam. Though there are more than 100 potential witnesses and more than 50 companies whose names could come up at trial, Mr. Streeter, who spoke for an hour, mentioned only a handful, focusing on what the government most likely considers the strongest evidence of insider trading.

Mr. Dowd used the government's uncluttered approach against it. "Unlike Mr. Streeter, I'm going to tell you about the entire case," he said. He did not disappoint. The defense lawyer's opening statement named dozens of companies in a presentation that clocked in at one hour and 40 minutes.

While Mr. Streeter used no visual aids, Mr. Dowd posted more than 30 pages of memos on an overhead display in the courtroom. Each focused on a company in which Mr. Rajaratnam is accused of trading on illegal tips. Mr. Dowd took the jury through each trade...

The jury can't make an informed judgment about the merits of the government's case against Rajaratnam without hearing the details, obviously (and not knowing the details, I offer no opinion on his guilt). But as this report suggests, an exhaustively detailed account is likely to favor the defense; confusion sows reasonable doubt. The prosecution, I assume, wants to present the jury with an outline of the forest; the defense wants it lost amid the trees -- where most of us wander, dependent on the guides we choose to lead us out.

Even when a dentist kills an adored lion, and everyone is furious, there’s loftier righteousness to be had.

Now is the point in the story of Cecil the lion—amid non-stop news coverage and passionate social-media advocacy—when people get tired of hearing about Cecil the lion. Even if they hesitate to say it.

But Cecil fatigue is only going to get worse. On Friday morning, Zimbabwe’s environment minister, Oppah Muchinguri, called for the extradition of the man who killed him, the Minnesota dentist Walter Palmer. Muchinguri would like Palmer to be “held accountable for his illegal action”—paying a reported $50,000 to kill Cecil with an arrow after luring him away from protected land. And she’s far from alone in demanding accountability. This week, the Internet has served as a bastion of judgment and vigilante justice—just like usual, except that this was a perfect storm directed at a single person. It might be called an outrage singularity.

Writing used to be a solitary profession. How did it become so interminably social?

Whether we’re behind the podium or awaiting our turn, numbing our bottoms on the chill of metal foldout chairs or trying to work some life into our terror-stricken tongues, we introverts feel the pain of the public performance. This is because there are requirements to being a writer. Other than being a writer, I mean. Firstly, there’s the need to become part of the writing “community”, which compels every writer who craves self respect and success to attend community events, help to organize them, buzz over them, and—despite blitzed nerves and staggering bowels—present and perform at them. We get through it. We bully ourselves into it. We dose ourselves with beta blockers. We drink. We become our own worst enemies for a night of validation and participation.

Forget credit hours—in a quest to cut costs, universities are simply asking students to prove their mastery of a subject.

MANCHESTER, Mich.—Had Daniella Kippnick followed in the footsteps of the hundreds of millions of students who have earned university degrees in the past millennium, she might be slumping in a lecture hall somewhere while a professor droned. But Kippnick has no course lectures. She has no courses to attend at all. No classroom, no college quad, no grades. Her university has no deadlines or tenure-track professors.

Instead, Kippnick makes her way through different subject matters on the way to a bachelor’s in accounting. When she feels she’s mastered a certain subject, she takes a test at home, where a proctor watches her from afar by monitoring her computer and watching her over a video feed. If she proves she’s competent—by getting the equivalent of a B—she passes and moves on to the next subject.

The Wall Street Journal’s eyebrow-raising story of how the presidential candidate and her husband accepted cash from UBS without any regard for the appearance of impropriety that it created.

The Swiss bank UBS is one of the biggest, most powerful financial institutions in the world. As secretary of state, Hillary Clinton intervened to help it out with the IRS. And after that, the Swiss bank paid Bill Clinton $1.5 million for speaking gigs. TheWall Street Journal reported all that and more Thursday in an article that highlights huge conflicts of interest that the Clintons have created in the recent past.

The piece begins by detailing how Clinton helped the global bank.

“A few weeks after Hillary Clinton was sworn in as secretary of state in early 2009, she was summoned to Geneva by her Swiss counterpart to discuss an urgent matter. The Internal Revenue Service was suing UBS AG to get the identities of Americans with secret accounts,” the newspaper reports. “If the case proceeded, Switzerland’s largest bank would face an impossible choice: Violate Swiss secrecy laws by handing over the names, or refuse and face criminal charges in U.S. federal court. Within months, Mrs. Clinton announced a tentative legal settlement—an unusual intervention by the top U.S. diplomat. UBS ultimately turned over information on 4,450 accounts, a fraction of the 52,000 sought by the IRS.”

There’s no way this man could be president, right? Just look at him: rumpled and scowling, bald pate topped by an entropic nimbus of white hair. Just listen to him: ranting, in his gravelly Brooklyn accent, about socialism. Socialism!

And yet here we are: In the biggest surprise of the race for the Democratic presidential nomination, this thoroughly implausible man, Bernie Sanders, is a sensation.

He is drawing enormous crowds—11,000 in Phoenix, 8,000 in Dallas, 2,500 in Council Bluffs, Iowa—the largest turnout of any candidate from any party in the first-to-vote primary state. He has raised $15 million in mostly small donations, to Hillary Clinton’s $45 million—and unlike her, he did it without holding a single fundraiser. Shocking the political establishment, it is Sanders—not Martin O’Malley, the fresh-faced former two-term governor of Maryland; not Joe Biden, the sitting vice president—to whom discontented Democratic voters looking for an alternative to Clinton have turned.

During the multi-country press tour for Mission Impossible: Rogue Nation, not even Jon Stewart has dared ask Tom Cruise about Scientology.

During the media blitz for Mission Impossible: Rogue Nation over the past two weeks, Tom Cruise has seemingly been everywhere. In London, he participated in a live interview at the British Film Institute with the presenter Alex Zane, the movie’s director, Christopher McQuarrie, and a handful of his fellow cast members. In New York, he faced off with Jimmy Fallon in a lip-sync battle on The Tonight Show and attended the Monday night premiere in Times Square. And, on Tuesday afternoon, the actor recorded an appearance on The Daily Show With Jon Stewart, where he discussed his exercise regimen, the importance of a healthy diet, and how he still has all his own hair at 53.

Stewart, who during his career has won two Peabody Awards for public service and the Orwell Award for “distinguished contribution to honesty and clarity in public language,” represented the most challenging interviewer Cruise has faced on the tour, during a challenging year for the actor. In April, HBO broadcast Alex Gibney’s documentary Going Clear, a film based on the book of the same title by Lawrence Wright exploring the Church of Scientology, of which Cruise is a high-profile member. The movie alleges, among other things, that the actor personally profited from slave labor (church members who were paid 40 cents an hour to outfit the star’s airplane hangar and motorcycle), and that his former girlfriend, the actress Nazanin Boniadi, was punished by the Church by being forced to do menial work after telling a friend about her relationship troubles with Cruise. For Cruise “not to address the allegations of abuse,” Gibney said in January, “seems to me palpably irresponsible.” But in The Daily Show interview, as with all of Cruise’s other appearances, Scientology wasn’t mentioned.

An attack on an American-funded military group epitomizes the Obama Administration’s logistical and strategic failures in the war-torn country.

Last week, the U.S. finally received some good news in Syria:.After months of prevarication, Turkey announced that the American military could launch airstrikes against Islamic State positions in Syria from its base in Incirlik. The development signaled that Turkey, a regional power, had at last agreed to join the fight against ISIS.

The announcement provided a dose of optimism in a conflict that has, in the last four years, killed over 200,000 and displaced millions more. Days later, however, the positive momentum screeched to a halt. Earlier this week, fighters from the al-Nusra Front, an Islamist group aligned with al-Qaeda, reportedly captured the commander of Division 30, a Syrian militia that receives U.S. funding and logistical support, in the countryside north of Aleppo. On Friday, the offensive escalated: Al-Nusra fighters attacked Division 30 headquarters, killing five and capturing others. According to Agence France Presse, the purpose of the attack was to obtain sophisticated weapons provided by the Americans.

The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.

What is the Islamic State?

Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.

Some say the so-called sharing economy has gotten away from its central premise—sharing.

This past March, in an up-and-coming neighborhood of Portland, Maine, a group of residents rented a warehouse and opened a tool-lending library. The idea was to give locals access to everyday but expensive garage, kitchen, and landscaping tools—such as chainsaws, lawnmowers, wheelbarrows, a giant cider press, and soap molds—to save unnecessary expense as well as clutter in closets and tool sheds.

The residents had been inspired by similar tool-lending libraries across the country—in Columbus, Ohio; in Seattle, Washington; in Portland, Oregon. The ethos made sense to the Mainers. “We all have day jobs working to make a more sustainable world,” says Hazel Onsrud, one of the Maine Tool Library’s founders, who works in renewable energy. “I do not want to buy all of that stuff.”

A controversial treatment shows promise, especially for victims of trauma.

It’s straight out of a cartoon about hypnosis: A black-cloaked charlatan swings a pendulum in front of a patient, who dutifully watches and ping-pongs his eyes in turn. (This might be chased with the intonation, “You are getting sleeeeeepy...”)

Unlike most stereotypical images of mind alteration—“Psychiatric help, 5 cents” anyone?—this one is real. An obscure type of therapy known as EMDR, or Eye Movement Desensitization and Reprocessing, is gaining ground as a potential treatment for people who have experienced severe forms of trauma.

Here’s the idea: The person is told to focus on the troubling image or negative thought while simultaneously moving his or her eyes back and forth. To prompt this, the therapist might move his fingers from side to side, or he might use a tapping or waving of a wand. The patient is told to let her mind go blank and notice whatever sensations might come to mind. These steps are repeated throughout the session.
